Why p3. The bucket-key table just above the sentence (
'year'→YYYY, …) is already right, so an author who reads the section gets the key shape right. What is wrong is the description of the engine behind it.Routing.

- The sentence names what each arm emits, read from the driver code at claim time: PostgreSQL, MySQL, SQLite, MongoDB and in-memory. Each arm is read, not carried over from this card. This card's body checked two of the five.
- It says the driver emits the bucket, and that the key is a label (

The ruling's "no other sentence in dashboards.md" line rested on the key table being right; the carrier's measured reading shows the week row is not, and the seat folds the family into this one PR rather than a second governed PR for two sentences (a documentation-out-of-sync item, no product behaviour, one human review). ⛔ No other file (stop on breach; explain in the report)

SqlDriver.buildDateBucketExpr(packages/drivers/driver-sql/src/sql-driver.ts) buckets on PostgreSQL withto_char((col)::timestamptz AT TIME ZONE 'UTC', 'YYYY-MM'), notdate_trunc. This was measured on PostgreSQL 16.14 during #21441 (os-dev report on #21441, PR #21587). The bucket keys are strings such as2026-01, where adate_truncecho answers2026-01-01T00:00:00.000Z.date_format(convert_tz(…))) and the MongoDB arm.Why it matters. The skill is the authoring surface agents read. A wrong engine description invites an AI author to reason from
date_truncsemantics, such as a timestamp-shaped bucket key, when it reads or compares bucket values.Who acts. Triage routes this.
